This year Henry will save a certain amount of his income, and he will spend the rest.  Next year Henry will have no income, but for each dollar that he saves this year, he will have 1 + r dollars available to spend.  In terms of r, what fraction of his income should Henry save this year so that next year the amount he was available to spend will be equal to half the amount that he spends this year?

  A.1/  r+2                      B.1/ 2r +2                       C. 1/ 3r+2             D. 1/  r+3                E. 1/2r+3

答案：E  算不出来，尤其是不明白第二行的he will have 1 + r dollars available to spend指的是明年的花费 还是今年和明年总的花费

还有一道语法的题目：

(B) of there being little that is significantly different

(C) of little that is significantly different

(E) that there is little of significant differences

答案是D,但是不是很明白D的句子结构啊
